Back after a long break - 2/4 River decision

[JrJordan]

Villain statss ay 17/12 but I think he's been playing tigher preflop during this session so far. We haven't tangled yet, but my image is a little weak after failing to take many c-bets so far.

My initial river bet probably should've been bigger, closer to $50. His hand range doesn't include much in the 2-5 range though given his tight preflop tendencies, but it is a blind battle so who knows he could have a 3. Not sure why he'd just call flop and check through the turn though. Is he raising my weak bet often enough to call here?
